Sirius spent a long time talking with his little brother before continuing his journey in the Land Beyond the Veil. He knew that when he returned there for good, it would be as though Hogwarts had never happened to separate the brothers, even better, really. But, he first had to return to the world of the living and die, again, many, many years from now. As well as face whatever new horrors the Veil had in store for him. Such as the building before him now, which had meant stuffy parties and gross food when he was still a child, and then the house of evil when he was a grown man and Auror. He didn't even bother to groan as he stared up at the imposing structure of Malfoy Manor. He knew the game by now; he would have to go in there and face whatever was there best he could.
So, without any further ado, Sirius marched into the manor. The inside seemed different than before; the walls and floors were a matching rusty red color that Sirius tried hard not to think on and the whole place seemed to be permeated with Dark Magic.
"Cissy, you've lost your decorating touch," he muttered under his breath as he crept toward the Grand Dining Room, going slowly as possible.
The room had been cleared of the great dining table that Sirius remembered, instead housing only a dais and two large throne-like chairs that seemed to be made of bone, though only was notably smaller than the other. Death Eaters stood silently in the room, seeming to cower before one of the thrones' occupants, who was, surprisingly, not Voldemort. Instead, it was a teenaged boy, probably around Bailey's age, with aristocratic features, light brown hair and cold grey eyes. He was smirking mischievously at the people cowering before them, as though he had just played some glorious prank. Like killing one of them.
Sirius stepped toward the boy, recognizing something familiar in him—the way he held himself, the dimples in his cheek—Sirius was fairly sure he had met the boy before. As he was about to step up onto the dais, he was stopped by the door opening to reveal old Snake Face himself. The Death Eaters all dropped to the floor, kissing Voldemort's feet. The boy, however, didn't bow. He instead kissed the maniac's ring, like Voldemort was a monarch of old or something.
"Bring in the prisoner," Voldemort ordered in his cold voice as he and the boy sat in their respective thrones. "Are you ready?"
"I was born ready, Father," the boy replied. Sirius had to take a step back. Someone had borne Voldemort a child? When had that happened? He felt sick, thinking of his cousin and her obsession.
"That's not true, Augustus," a new voice came. Between two masked Death Eaters was a woman who looked like she was in her fifties, though Sirius could feel the untruth in her appearance. She pulsated with wild power, even though she looked as though she had been tortured and starved for years.
"What is not true, Lady Black?" Voldemort replied with a smirk curling his unnatural features. Sirius felt a chill go down his spine at his words; that emaciated figure was his daughter?
Bailey's eyes did not leave the boy; yet, instead of loathing like Sirius would hope his daughter would show for the progeny of Voldemort, Bailey seemed to be in deep pain, love for the boy shining out from every pore.
"You don't remember the day o' your birth, Gussy, I do. And you were not born fer this," she said sadly, voice cracking with emotion.
"What is the prisoner talking about, Father?" the boy said, his mask of boredom seemingly cracking.
"Nothing of import, my heir," replied Voldemort coldly.
"I was there, seventeen years ago today," she cried, looking straight at the boy. "Dad had died, but you, yeh gave Mum so much hope. Hope that I should have held tight to as well. She was so, so happy. And I am so sorry, baby brother. You and Mum paid for me mistakes. But, this is not what you were meant for. I tried, I tried so hard to run—to protect you—but they found us. I am so, so sorry, baby brother."
Sirius gaped between his daughter and the boy, suddenly realizing what he had found so familiar about Voldemort's so-called heir. The boy before him had his mother's dimples, her hair, Sirius' own eyes. Even though Bailey was so sickly looking, anyone with eyes could tell that the two were related. They were siblings. The boy—Augustus—was his son.
"I think dear Bella has scrambled our prisoner's head a bit too much," Voldemort said to laughter from the crowd of Death Eaters. But Augustus was staring down Bailey, who was quietly crying.
"And what happened to 'Mum'?" he said in low voice as he stalked towards her. Sirius recognized the haunted look in his son's eyes. He was remembering something horrible.
"She begged me," Bailey said, hanging her head. "She begged me to protect you, make sure you were kept alive, no matter what—"
"And what did you do?" Augustus said in a dangerous voice. Sirius begged his daughter not to answer. His son grabbed her chin, forcing her to look up into his eyes. "Say it!"
"Please, don't make me, Gussy," she begged.
"Don't call me that, you filthy blood traitor," he snarled. "Tell me what happened and learn some respect for your betters, Lady Black."
She looked up at him, searching for something in him. A look of utter despair came over her when she found what she was looking for. "You remember?"
"Tell. Me."
"Fine. If that makes it easier to do what yeh 'ave to do," she said, emotion causing her accent to come through even stronger than before. It seemed not even Narcissa's lessons could overcome punishments given by the Dark Lord. "I killed 'er, Gussy. I'm so sorry, Gussy, I did wha' she asked o' me. I couldn' let 'er suffer anymore fer me mistakes. I—"
She was not able to say anymore as then Augustus muttered a couple of words, jabbing his wand towards his sister, and suddenly cuts appeared all over his sister's body. She sunk to the floor, choking for air.
"Love—you—baby—broth—" she gasped out before her eyes went glassy. Sirius collapsed by his daughter's side.
"How could you, both of you?" he howled. "She was your mother, and she—she was your sister! What is wrong with you, both of you?"
Augustus did not seem to hear; instead he just looked down at his sister, a single tear appearing in his eye, before he turned back to the Death Eaters and Voldemort.
"Our greatest traitor is DEAD!" he shouted. Cheers went up all around him as Voldemort slowly rose and made his way toward Augustus, taking the boy into a firm embrace. Sirius jumped up, ready to tear the man apart, limb by limb, for daring to touch one of his children.
"Well done, my son," Voldemort whispered coldly into his ear. "Your training is complete. All, turn and pay homage to your new Dark Prince!"
With that, the Death Eaters all fell to the floor, kissing Augustus' feet just as they had Voldemort's. Sirius felt bile rise in his throat as the scene disappeared before him, making him dizzy.
He had a son. He had a son.
